利用攔截器對spring的controller進(jìn)行了攔截，實(shí)現(xiàn)代碼如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<context:component-scan base-package="com.example" />
<bean id="handlerMappingTemplate" abstract="true">
<property name="interceptors">
<list>
<bean class="com.example.aspect.LoginCheckInterceptor" />
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" parent="handlerMappingTemplate" />
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" parent="handlerMappingTemplate" />
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/app/" p:suffix=".jsp" />
</beans>
具體的java類代碼也比較簡單
package com.example.aspect;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
public class LoginCheckInterceptor extends HandlerInterceptorAdapter {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
System.out.println("\n\n\n\n\n"+request);
throw new Exception("用戶沒有該操作的權(quán)限！");
}
}
